ABSTRACT:
On an optical disk medium according to the present invention, address information is recorded along a wobbling track groove2.The track groove2is made up of a plurality of unit sections22, 23.Each of these unit sections22, 23has side faces that are displaced periodically in a disk radial direction. This displacement oscillates at a single period in a tracking direction. However, the displacement pattern differs depending on “each bit of address information (subdivided information)” allocated to each of the unit sections22, 23.
